Code P16AE 2015 Chevrolet Silverado Description

The Glow Plug Control Module (GPCM) has the ability to perform internal diagnostics for the temperature sensor circuit. The GPCM monitors the internal temperature sensor voltage and if the voltage is less than 0.21 V or greater than 4.94 V. The GPCM will send a message to the Engine Control Module (ECM) to set the appropriate Diagnostic Trouble Code (DTC). A DTC is detected when one of the GPCM temperature sensors voltage falls outside the calibrated threshold for greater than 1.3 s.
